sparc64: fix warnings in psycho_common after ull conversion
After conversion to use unsigned long long for u64
I saw following warnings:
CC arch/sparc/kernel/psycho_common.o

This is due to different integer promotion in my 32 bit hosted gcc.
The fix is to force a few constants to ULL.
The following stands out from the rest:
+#define PSYCHO_IOMMU_TAG_VPAGE 0x7ffffULL
+#define PSYCHO_IOMMU_DATA_PPAGE 0xfffffffULL
They were needed otherwise the expression:
(data_val & PSYCHO_IOMMU_DATA_PPAGE) << IOMMU_PAGE_SHIFT)
were promoted to a unsigned long and not a unsigned long long as expected.
I tried the alternative solution and made IOMMU_PAGE_SHIFT an ULL but that did not help.
The only way gcc would make this expression an unsigned long long was to
define PSYCHO_IOMMU_DATA_PPAGE as ULL. The alternative to add a cast was
not considered a valid solution.
We had this issue in two places and this were the only places the above
two constants are used.
A small coding style diff sneaked in too.
